Auction process for Fixed Income Liquidation Group

Auction process for Fixed Income Liquidation Group (LG)

For interest rate swaps each Clearing Member can chose which currencies it wants to clear, and consequently it has to participate only in those auctions, which relate to the Clearing Member’s chosen currencies.

With respect to the Fixed Income LG, Eurex Clearing conducts one single unit auction for each currency comprised in the defaulted Clearing Member’s portfolio. Eurex Clearing discloses the auction portfolio to all auction participants, each auction participant provides one price for the entire portfolio and the highest price wins.

If margin offsets were granted between the defaulted Clearing Member’s interest rate swaps and its listed fixed income derivatives (cross margining), the relevant products will be liquidated simultaneously.
The auction format and procedure described here applies either for a portfolio containing interest rate swaps and listed fixed income derivatives, or for a portfolio containing only interest rate swaps. If a defaulted Clearing Member’s portfolio contains listed fixed income derivatives only, Eurex Clearing conducts a multi-unit auction (the auction format used for the Equities Derivatives LG) to allow for the broadest possible range of auction participants. 

A positive price indicates an amount to be paid by the winning auction participant to Eurex Clearing. A negative price indicates an amount to be paid by Eurex Clearing to the winning auction participant.

A Clearing Member is exempted from participation in an Fixed Income Derivatives auction, if the Clearing Member has not conducted any transaction in the Fixed Income LG within the last three months prior to the default.

 

Failure to comply with bidding requirement

If a Clearing Member, who is obliged to participate in an auction for the Fixed Income LG, fails to do so, such failure results in a monetary fine. The exact fine depends on the relative size of the non-bidding Clearing Member compared to all other Clearing Members (in terms of Default Fund contribution), but is in any case capped at EUR 5 million.

To incentivize competitive bidding, a method defining the order in which non-defaulted Clearing Members' Default Fund contributions would be utilized has been established. Depending on the relative quality of a Clearing Member’s price, such Clearing Members' Default Fund contribution is either juniorized or seniorized. All juniorized contributions will be utilized before any seniorized contributions are used, whereas on each "level" contributions are used on a pro rata basis across all relevant Clearing Members.

Determination of auction prices

To determine the relative quality of Clearing Members’ prices, Eurex Clearing classifies each Clearing Member’s auction price as "sufficient", "medium" or "insufficient". A price is "sufficient", if the difference between the winning auction price and this price is less than 0.5 times the initial margin requirement for the auction portfolio. A price is "insufficient", if the difference between the winning auction price and this price is more than 1.5 times the initial margin requirement for the auction portfolio, and a price is "medium", if it is anywhere between these thresholds. Default Fund contributions of Clearing Members who submitted "sufficient" bids are seniorized, Default Fund contributions of Clearing Members who submitted "insufficient" bids are juniorized, and Default Fund contributions of Clearing Members who submitted "medium" bids are partly juniorized and partly seniorized.

Listed fixed income derivatives can be either options or futures. All futures and future style options (i.e. all listed derivatives in the Fixed Income Liquidation Group) have a value of zero at the beginning of each business day. The relevant cash flow relating to these products is the variation margin resulting at the end of the auction day. As such, when pricing futures positions or future style option positions in a default management auction, it is essential that Clearing Members do not price-in the face value of such positions. Rather, the price provided by a Clearing Member, needs to reflect the Clearing Member’s expectation of variation margin payments that will become due for the respective positions at the end of the auction day.
